Fluxbox window manager

[12/15/2017]
Added a few theme variants, based on tenr.de themes. Minor
changes in each, but important to me. Mostly, I can't use
themes that don't have a large enough resize handle. I also
don't generally like themes that are chunky in the window
decorations... except where it's functionally important,
like the resize handle :) But even that can be overdone,
as in the fluxbox amiga theme (though, it's just trying to
be an accurate reproduction, so there is perhaps a purpose
there...)

laser_blue_mod and trinity_mod satisfy my own needs/wants
by modifying two themes that I mostly like. They're dark
themes, which I go to every once in a while.

I have a few more modified themes that I will try to
upload here, for what they're worth. Again, these aren't
themes I've created, they're just slight modifications.
